Early structure formation from cosmic string loops in light of early JWST observations

Refregier, Alexandre; Jiao, Hao; Brandenberger, Robert

Cosmic strings, if they exist, source nonlinear and non-Gaussian perturbations all the way back to the time of equal matter and radiation (and earlier). Here, we compute the mass function of halos seeded by a scaling distribution of cosmic string loops, and we compare the results with the predictions of the standard Gaussian Λ cold dark matter mod…
